A method of designing a semiconductor device includes creating a library for test patterns on a frame and an on purpose violation layout on a main chip of a layout, and then creating filter marks according to the library. An OPC (optical proximity correction) is run using the layout, and an OPC verifying is performed for obtaining a pattern with hot spots to determine whether the hot spots are within the frame and the filter marks. When the hot spots are within the frame and the filter marks, a mask can be made. When the hot spots are outside the frame and the filter marks, it is necessary to check whether the hot spots need to be repaired. When the hot spots are within the frame and outside the filter marks, the hot spots are added into the library as data of the on purpose violation layout.
